Climate activists, oil executives, atmospheric scientists , and investors are all trying to make sense of the same picture using completely different language and with vastly different priorities. And this week was a particularly striking example of this split screen.  Policymakers and climate advocates gathered at a global summit to phase out fossil fuels .
